Be it known that we, JOHN FLOQD and' J0- SEPH KIPLING, citizens of the Dominion of Canada, residing at Quebec, in the Province of Quebec, Canada,have invented certain new and useful Improvements in Apparatus for Generating Acetylene Gas; and we do hereby declare the following t0 be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

This invention relates to gen erators for acetylene gas; and it consists in the novel construction'and combination of the parts hereinafter fully described and claimed.

The drawing shows a sectional diagrammatic view of the.apparatus.

A A are closed vessels in which are placed perforated receptacles a for holding carbid of calcium or other similar metallic carbid from which acetylene gas may be generated.

B is a closed vessel containing water in its lower part and gas in its upper part. A pipe B is adapted to let the water out of the vessel B, and b are branches provided with valves b', which connect the pipe B with the lower parts of the vessels A and A', respec- C is a pipe for conducting the gas into the upper part of the vessel B, and c are branch pipes connecting the pipe C with the upper parts of the vessels A and A', respectively.

The generation of gas is arranged to take place alternately in the vessels A and A' byv closing the valvesin the branch pipes. In this manner the production of gas is constant, and one vessel can be recharged with carbid while the other is in action. The pipe B has avalve-chamber D and an extension d inside the vessel B. The extension d has a branch d', through which the water enters it. f

D is a valve in the chamber D, and E is a rod which couples the valve Dl to a flexible plate E', of india-rubber, inside a vcasing c at the top of the vessel B. A spring e' is arranged over the plate E to prevent'it from rising too freely.

F is a leverpivoted to a lug f on the branch d' and provided with a valve f for closing the mouth of the said branch. G is a rod which connects the free end of the lever F with a spring-pressedplate g, of flexible material, inside a casing g. at the top of the vessel B.

i .H is a gas-filter arranged at the top of theA vessel B, and his an opening at its lower part connecting it with the said vessel.

The filter H is provided with two layers of absorbent cotton H' and a layer of charcoal h', interposed between the said layers of cotton. I

I is a second gas-filter, and I is a perforated vessel inside the said filter I. A second perforated Vesselrl is arranged inside the vessel I. The Vessel t' is filled with absorbent cotton if, and the space between the two vessels I' and t is packed with charcoal j.

J is a pipe connected to the upper part of the filter H and provided with a regulatingvalvej. The pipe J. passes into the second ilter I and is provided with a valve-chamber K at its end. A valve lc is arranged in the chamber K.

L is a spindle suspending the valve k from a plate k', of iexible material, 'provided with a spring at its upper side andinclosed within a chamberyL, which is connected to the top of the filter I.

M is a gas-receiver,-and fm is a pipe connected to the perforated vessel 1I and projecting within the receiver M.v The upper end portion of the pipe m vis provided with a inside a chamber N at the top of the re- .ceivein O isa distributing-pipe for the gas, connected to the said receiver.
